Is this normal???
Coolant temp isn't over heating at 104, or 107C. In fact depending on how you are driving, or the ambient temps, it can be quite normal. Get a scanner, and check for trouble codes, if none are present, I wouldn't worry. If you are above 75K miles on the odometer, change your water pump, and thermostat.
